This invention relates to skylights, and will be best understood by reference to the following description, when taken in connection with the accompanying drawings of one specilic embodiment thereof, while its scope will be more particularly pointed out in the appended claims.

In the drawings Fig. 1 is a plan of a portion of a s ylight embodying the invention;

Fig. 2 is a sectional view, on an enlarged scale, on line 22 of Fig. 1;

Fig. 3 is a perspective view of one end of one of the cross-gutters and the rabbet memher which supports it;

Fig. 4: is a sectional View, on an enlarged scale, on line 14 of Fig. 1.

Fig. 5 is a sectional view on line 55 of Fig. 4;

Fig. 6 is a sectional view, on an enlargec scale, on line 66 of Fig. 1;

Fig. 7 is a perspective view of a portion of the skylight;

Fig. 8 is a perspective View of the bracket, or base cradle, which supports the lower end of each T-bar.

Fig. 9 is a sectional view, on an enlarged scale, on line 99 of Fig. 2, illustrating one of the clips or saddles and its stud; and

Fig. 10 is a sectional view, on line 10-1O of Fig. 9.

Referring to the drawings, and to the embodiment of the invention which is illustrated therein, and having reference at first to Fig. 2, there is shown a glazed structure comprising two glass members 15, having adjacent edges separated by a space 16. These members are supported by an underlying sup port, herein a T-bar 17, having a vertical web 18 and two horizontal flanges 19.

Superimposed upon the T-bar is a gutter member 20, usually of non-ferrous sheet metal, bent downwardly and inwardly about the flanges 19 to embrace the T-bar, thence downwardly and finally upwardly, to provide gutters or troughs 21. The gutter member is assembled with the T-bar by sliding one lengthwise onto the other.

' Superimposed upon the gutter member is a clio or saddle 22, also usually made of non- 1928. Serial No. 291,623.

ferrous sheet metal, which is first laid upon the gutter member at the proper point, and then has its ends bent downwardly and inwardly beneath the flanges 19, in the same form as the gutter member. This clip or saddle provides a mounting for a stud 23, of non-ferrous, or non-corrosive metal, which is conveniently held against turning movement with relation to the clip (see Figs. 9 and 10), as by providing the clip with a depression 2 1 of non-circular formation, and the stud with a head 25 of corresponding formation received in the depression. In the present example, the head of the stud or screw is slabbed on opposite sides to provide two flat faces 26, which are received between corresponding surfaces of the depression.

Referrii now to Fig. 2, this stud extends upwardly through the space 16 between the glass members 15, and through a cap 27,

herein a channel-like bar of suitable noncorrosive metal having downwardly directed edges 28, which rest upon a strip of cushioning material, such as saturated felt 29, superimposed upon and spanning the adjacent edges of the glass members. A similar, but much thicker strip of cushioning material 30, such as felt, is interposed between the glass members and the gutter member. These two strips of cushioning material are of course perforated at intervals to receive the studs or clamping screws. A nut 31 and a washer 32, applied to the screw, urge the cap toward the underlying parts, and thus clamp them to the T-bar, and compress the strips of cushioning material, thus making a tight joint. It should be understood, of course, that each cap is secured to the underlying T-bar by an appropriate number of the clamping studs (see Fig. 1).

Referring now to Fig. 6, the T-bar constitutes a rafter whose upper end is secured to a ridge, herein a plate 33, as by angle brackets 3 1 and bolts 35 and 36. The upper edges of the glass members are received in grooves 87 presented by a ridge cap 38, herein made ofnon-ferrous sheet metal bent into the desired form. The lower end of the bar (see Fig. 4:) is supported by an appropriate support, herein a bracket or base cradle 39 (best shown in Fig. 8), which is provided with a channel 40 to receive the downwardly directed web of the T-bar. Referring again to Fig. l, these cradles are suitably supported, as by being secured by bolts 41 extending through lateral flange 42 presented by the cradles, through an underlying sheet metal apron 43, through continuous angle plates i l, and through brackets so, the latter being secured as by lag screws 46 to a curb 47. In the present example, the channel lO does not extend entirely through the cradle, but terminates a suiiicient distance below the lowerend of the latter to provide an abutment as, which is adapted to limit downward lengthwise movement of the bar. Herein, this abutment is provided with a drain opening 49 leading from the channel for the escape of moisture therefrom. In this instance, the bar is secured to the cradle, and is prevented from being lifted therefrom by air pressure or other disturbances, as by a rivet 50 which extends through the sides of the cradle and through the web of the bar.

An apron 51, usually of non-ferrous sheet metal, closes the outer side of the structure, and is bent to provide a shoulder 52 below the lower edge of the glass member, and a 53 beneath the upwardly sloping lower face of the latter. To prevent any downward thrust of the glass member against this shoulder from causing outward displacement of the apron, there is provided suitable means, here in a key plate 54rbelow said shoulder and interlocked with the cradle as by providing the latter with a transverse notch 55, in which the plate is received. Lateral displacement of the plate is prevented, as by providing the plate with downwardly directed lugs 56 (see Fig.- 5) straddling the craddle. This plate is pref-x erably made of suitable non-corrosive ma. terial. The cradle may be a malleable iron casting. After the, plate has been dropped into place in the notch, it may be secured therein by striking the adjacent end of the cradle with a hammer, to'bend the cradle inwardly at that point to grip the plate. After the apron has been put inplace, it locks the plate in thevcradle. The apron is provided thereto what I claim and desire b Letters latent to secure is 1; In a skylight structure, the combination of glass members having adjacent edges separated by a space, an underlying support, a

gutter member superimposed upon said support and extending downwardly and inwardly on both sides to embrace said support, a clip superimposed upon said gutter member and extending downwardly and inwardly on both sides to embrace said support and part of said gutter member, a stud secured to said clip and extending upwardly through said space, and means cooperating with said stud to hold said glass members in place.

2. ln a sh light structure, the combination of glass members having adjacent edges separated by a space, an underlying support, a sheet metal clip lying fiatwise upon said support and bent downwardly and inwardly on both sides to embrace said support, said clip being pro *ided with an opening, a stud having a head below said opening and a shank extending upwardly through said opening and through said space, said stud having a non-circular head and said clip having a non-circular depression which receives said head and prevents rotation of said stud relatively to said clip, the bottom of said head being substantially flush with the lower face of said clip, and a nut on said stud to hold said lass members in place.

In testimony whereof, I have signed my 7 name to this specification.

with drain openings, one of which is shown at 57. It should be understood, of course, that the glass members are provided with rabbet strips 58, which extend between the adjacent edges of the glass-members, and are bent to provideoppositely extending upper and lower flanges 59 and 60, the latter having a return bent portion 61, which is provided with a downwardly directedlip 62 to cause any moisture which collects to drip therefrom into a cross-gutter 68 The glass members are sometimes bedded into this rabbet str p 7 with cement or putty.
